Title: Production of wax pattern
Inventor: MIYAZAKI TOMOAKI
IPC: B22C9/04
Filed: 1986-03-31
Abstract: PURPOSE:To decrease the amt. of the costly wax to be used so as to permit the easy transfer and handling of a tree and to shorten the time for dewaxing by using a shape memory alloy which diminishes dimensionally in the longitudinal direction at a dewaxing temp. to form the main parts of the sprue bar of the tree. CONSTITUTION:The cylindrical sprue bar 2 is formed of the shape memory alloy which is deformed at the temp. above the waxing temp. and not in excess of the dewaxing temp. The wax is attached to the sprue bar 2 and the top end face of the aprue bar 12 is closed by the wax and is waxed to a product pattern. The waxed product pattern is fixed to the waxed sprue bar and a ceramic layer is stuck and formed around the product pattern and sprue bar which are united to one body. The assembly is then heated to the dewaxing temp. to remove the wax. The shape memory alloy is deformed, shrunk and detached downward, by which the dewaxing from the product pattern is quickly progressed and the injury of the shell is prevented. A casting mold is completed upon completion of the dewaxing.

Title: Fm-cw radar apparatus
Inventor: KAWAKUBO JUNJI
IPC: G01S7/28
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To obtain an FM-CW radar apparatus in which a desired frequency modulation can be maintained when a change by aging exists, by a method wherein beat-signal frequency spectrums in every small section are compared and a control signal is corrected when the linearity of modulation at a transmitting signal collapses. SOLUTION: A voltage-controlled oscillator 11 outputs an oscillation frequency which is proportional to a control voltage given by a D/A converter 20. Electromagnetic waves are radiated from a transmitting antenna 13. A reflected wave signal from a target received by a receiving antenna 14 is mixed with a transmitted signal by a mixer 16, and the beat signal of both signals is fetched. An FFT processor 22 to which the signal is inputted generates the frequency spectrum of the beat signal between the up section and the down section of triangular waves. A correction device 23 finds and compares the Q value of a frequency spectrum A and that of a frequency spectrum B between a small section A and a small section B which are found by the FFT processor 22.  The Q values are large in a region in which the linearity of a modulation is maintained, and they are small in a region in which the linearity collapses. As a result, when the Q value A < the Q value B (or the Q value A > the Q value B), the control voltage in the small section B (or A) is corrected.
